No parameterless constructor defined for this object.

I just downloaded 2.80 version and run (no changes).
I have got such error on install action.
Please, tell me what is wrong with my environment (installed all versions of MVC).

I haven't got any answer yet. Here are the details of my environment.
VS ultimate 10/11 (package with source code), .installed .net 2/3/4/4.5 and MVC 2/3/4. Win 7 x64

When i run Nop.Web of version 2.65/2.7/2.8, i have got the following message in method FindClassesOfType
Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.
innerexception is
Could not load file or assembly 'System.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

After that i tried to install MVC 1 and got following error

No parameterless constructor defined for this object.

Thanks in advance

Hi,

Are you sure you have not customized any of the nopCommerce code?
The No Parameterless construct could be due to Autofac not being able to resolve the dependency of the InstallController, which is IInstallationLocalizationService.

As to the other error you are getting it simply means that the .NET loader is not being able to find the assembly referenced.
Check that your reference to System.Web.MVC is being resoved from here:

\packages\Microsoft.AspNet.Mvc.4.0.20710.0\lib\net40\System.Web.Mvc.dll

Thank you very much for quick response.
I'm sure . I just downloaded nopCommerce 2.80 - Source code extracted it and run ( I haven't done any changes).
Also checked the references to System.Web.MVC is being resolved from here
\packages\Microsoft.AspNet.Mvc.4.0.20710.0\lib\net40\System.Web.Mvc.dll

I guess something wrong with my environmental but unfortunately i getting those error and on my work's laptop and on my home's laptop.

Any idea to check my environment ?

Thanks in advance

Autofac 2.6.3.862 and Autofac ASP.NET MVC3 Integration 2.6.3.862 installed as well

please provide me how can i fix this issue.

Thanks in advance

Did anyone solve this?
I am on version 3.8 and it was working fine all day but now will not open the admin page. It just gives the below but the opening appears to be exactly the same error, if three years later. I have tried removing any new plugins and restoring all the system files but as I haven't changed anything it seems a bit pointless:


Server Error in '/' Application.

Usually when the admin page returns a page not found error, you should clean and rebuild the source and the error goes away.
Are you able to rebuild the Nop.Admin?
